An investigation on the effects of emerging 4G transmissions on 3G networks

Within the last 10 years, technological advances have allowed personal wireless communications to become part of our global, information-centric culture. Cellular telephones, personal digital assistants, and wireless computer networks allow for tetherless use anytime and almost anywhere. These wireless communication advances have quickly matured through three technological generations. Currently, wireless communications are considered to be in the third generation (3G) of deployment and are rapidly approaching the fourth (4G). As these wireless technologies advance to meet market demand, careful pre-market technical analysis of these new capabilities must be made to understand potential impact on existing communication systems. This paper provides a novel examination into the effects of 4G ultrawide band (UWB) signaling on a 3G wireless fidelity (WiFi) system. Through empirical and statistical analyses, we show that the throughput performance of the Wi-Fi system can be negatively impacted by up to 20%. We conclude that careful implementation of emerging 4G UWB systems must occur to mitigate the detriments to existing 3G communication systems.

网络传播的出现与传统媒体的回应

网络传播正在对传统媒体产生广泛而深远的影响。报纸、广播、电视三大传统媒体的社会分工不再像以前那样明确固定,而与网络媒体逐渐走向兼容并蓄,传统媒体与网络传播两者间的互动进一步加强。应在双向传播中整合新闻信息资源,拓展网络广告和电子商务,抢占国家“虚拟边疆”等。     

传播媒介的使用与误用——雷蒙德·威廉斯的传播异化批判理论

雷蒙德.威廉斯是英国文化研究的开拓者之一,在文学、文化与社会等研究领域取得了巨大的成就,但他在传播领域所进行的革命性探索却很容易为人们所忽视,这种探索也并没有为后来的英国文化研究者所继承。在传播媒介无孔不入的今天,如何建构一种真正健康的大众文化,从而建构一个文化民主的共同体,是我们要面对的问题。重新审视威廉斯的传播思想会让我们有所收获。     

Online authority communication during an epidemic: A Finnish example

Social media are creating new challenges for authority communications during crises, such as a pandemic. This study examined Finnish citizens’ opinions about authorities as crisis managers during the swine flu epidemic of 2009-2010 and examined the success of authority intervention to online discussion forums. Through a content analysis carried out at the discussion forums, the study showed that though authorities are highly trusted in general in Finland, this trust is not extended to the online environment. Online, civilians did not trust authorities and the protective actions taken. Moreover, the authorities’ intervention to the discussion forums aimed at correcting false information and shaping opinions seemed to fail, as the intervention was carried out too late and with too little resources. The paper calls for more proactive authority communication that would establish a dialogue with citizens before a crisis to ensure credibility during difficult times.
